Social insect colonies contain multiple phenotypes, i.e. castes, and this caste polyphenism is often linked to sexual dimorphism. Unlike social hymenopterans, both termite sexes are diploid and contribute to helper-type tasks within the colony. Nonetheless, a biased sex ratio is frequently observed in termites, especially in soldiers. To explain this bias(More)
T he genus Pediococcus includes Gram-positive, catalase-negative, and oxidase-negative lactic acid bacteria (1). Most of the known pediococcal strains were isolated from various plants and fruits, fermenting vegetables, beer, and silage. Genome sequences have been published for Pediococcus acidilactici (2), P. claussenii (3), and P. pentosaceus (4). P.(More)
One of the principal features of eusocial insect societies is the reproductive division of labor, which involves developmental regulation of the reproductive organs. However, although the regulation of caste development is important for establishing social structure in termites, one of the major eusocial insect groups, little is known about reproductive(More)
Sex-specific genetic markers are often required for studying sex-associated phenomena. Restriction site-associated DNA sequencing (RAD-seq) allows detection of a huge number of genetic polymorphisms and is particularly useful for identifying sex-specific DNA-based (or molecular) genetic markers. Although sex determination in the Japanese subterranean(More)
Combining single-cell methods and next-generation sequencing should provide a powerful means to understand single-cell biology and obviate the effects of sample heterogeneity. Here we report a single-cell identification method and seamless cancer gene profiling using semiconductor-based massively parallel sequencing. A549 cells (adenocarcinomic human(More)
